论文摘要
在本文中，基于线性参数变化（LPV）框架，为全范数氧化还原流量电池（VRB）系统开发了电解质流量控制方法。电解质流速受到调节，以在堆栈电压效率和泵送能量损耗之间提供权衡，以实现最佳的电池能量效率。非线性过程模型嵌入了线性参数变化的状态空间描述中，并且一组状态反馈控制器旨在处理充电和放电期间电流的波动。在不同的工作条件下进行了仿真研究，以证明所提出的方法的性能。这种控制方法进一步在实验室量表VRB系统上实施。
In this article, an electrolyte flow rate control approach is developed for an all-vanadium redox flow battery (VRB) system based on the linear parameter varying (LPV) framework. The electrolyte flow rate is regulated to provide a trade-off between stack voltage efficiency and pumping energy losses, so as to achieve optimal battery energy efficiency. The nonlinear process model is embedded in a linear parameter varying state-space description and a set of state feedback controllers are designed to handle fluctuations in current during both charging and discharging. Simulation studies have been conducted under different operating conditions to demonstrate the performance of the proposed approach. This control approach was further implemented on a laboratory scale VRB system.
